<1 and <2 form a linear pair. If m<1= 4m<2, find the measure of each of the two angles.
Answer:
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°Step-by-step explanation:
We know that when two lines meet or intersect, we get a linear pair of angles.
Linear pairs are basically two adjacent angles that form a line.
The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
We are given that <1 and <2 forms a linear pair, and
m∠1 = 4m∠2
It means the angle ∠1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
x + 4x = 180
5x = 180
divide both sides by 5
5x/5 = 180/5
x = 36°
Therefore,
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°2. u + 6y = 32
u+ 3y = 17

Answer:
78 m
Step-by-step explanation:
We need to use the Pythagorean theorem, [tex]a^{2} + b^{2} = c^{2}[/tex].
Substitute in [tex]a[/tex] and [tex]b[/tex].
[tex]30^{2} + 72^{2} = c^{2}[/tex]
Simplify.
[tex]900 + 5184 = c^{2}[/tex]
Add.
[tex]6084 = c^{2}[/tex]
Square root both sides.
[tex]78 = c[/tex]
The hypotenuse is 78 m long.
find c:
a² plus b² = c
72² plus 30²=c
5I84 plus 900
6084
now square root that
78
so C=78

y = x - 1
x + 4y = 16
Im having troubles. Can some 1 explain in complete explanations and all expressions.
{x,y} = {4, -3}
Substitution :
// Solve equation [2] for the variable x
[2] x = 4y + 16
// Plug this in for variable x in equation [1]
[1] (4y+16) + y = 1
[1] 5y = -15
// Solve equation [1] for the variable y
[1] 5y = - 15
[1] y = - 3
// By now we know this much :
x = 4y+16
y = -3
// Use the y value to solve for x
x = 4(-3)+16 = 4

10% of electric light bulbs are defective at manufacturer. A random sample of 8 light bulbs are chosen and tested. Find the probability that at least 3 are defective.
Answer:
0.0381
Step-by-step explanation:
This is a binomial probability distribution problem. Thus;
p = 10% = 0.1
We are told that A random sample of 8 light bulbs are chosen and tested. Thus, n = 8
We want to find the probability that at least 3 are defective. This will be;
P(X ≥ 3) = P(3) + P(4) + P(5) + P(6) + P(7) + P(8)
P(X = x) = C(n, x) × p^(x) × (1 - p)^(n - x)
Thus;
P(3) = C(8, 3) × 0.1³ × (1 - 0.1)^(8 - 3)
P(3) = C(8, 3) × 0.1³ × 0.9^(5)
P(3) = 0.03306744
Repeating this same procedure, we have;
P(4) = 0.0045927
P(5) = 0.00040824
P(6) = 0.00002268
P(7) = 0.00000072
P(8) = 0.00000001
Thus;
P(X ≥ 3) = 0.03306744 + 0.0045927 + 0.00040824 + 0.00002268 + 0.00000072 + 0.00000001 = 0.03809179
Approximately 0.0381
